Pure water is assumed to be pH 7, right in the middle. It is neither an acid nor a base.
There is no value of 11 on the pH scale. The pH scale ranges from 0 to 14, with 7 being neutral. A pH of 11 would be considered alkaline or basic.
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
Another name for a base might be alkali, but there is actual a subtle difference.
The pH scale is from 1-14 Strong acids are 1-4
A base is anywhere from 8 to 14 on the Ph scale. If a base of about 8 is added to and acid of about 6, the Ph will be balanced out.
Anything from above 7 to 14 is a base on the pH scale
A soluble base is an alkali, so above 7 on the pH scale.
The strongest base is the hydroxide ion, in the pH scale 0 to 14.
A basic pH is over 7.
A basic pH is under 7.
it indicate the acid and base of the scale
Pure water is assumed to be pH 7, right in the middle. It is neither an acid nor a base.
Bases run from 7.1 to 14 on the ph scale. A strong base would be in the 12-14 range. A 3ph is a relatively strong acid.
A strong base would be around from 1-3 on the pH scale.
pH ranges from 0-14, 7 being neutral, under that acid, above base.
There is no value of 11 on the pH scale. The pH scale ranges from 0 to 14, with 7 being neutral. A pH of 11 would be considered alkaline or basic.
